Question

8 multiple choice 1 point when a covalent bond forms, the potential energy of the atoms increases. decreases. remains constant. becomes zero.

Explanation:

In covalent bond formation, atoms share electrons to achieve a stable electron configuration. Stable configurations have lower potential energy. When bonds form, energy is released (exothermic), meaning the potential energy of the atoms decreases. The other options are incorrect: increasing would mean instability, remaining constant ignores energy changes, and becoming zero is not accurate as potential energy relative to a reference, not absolute zero in this context.

Answer:

B. decreases.
